The guidelines bellow are apliable to xyz-mIoT shield modemless version! PN like: XYZMIOT209#NOMODEM-000-xxxxxxx.
Direct drive powering for xyz-mIoT modemless shield
Connect the power supply to LIPO+ and GND pads, as shown bellow.
a. power supply voltage must be between 3.3V and 5.25V. Do not exceed those values!
b. no special requirements for power supply - typical consumtion is around tens of mA. If you power some periferals from 3.3V pad, take this consumtion into account.
c. if you want to use 5V from USB as power supply, simply connect Vusb(out) to LIPO+ pad.
LiPO baterry powering for xyz-mIoT modemless shield (and solar charger guidelines)
Connect the power supply to Vraw and one of GND pads in proximity and the LiPO/ LiION battery, as shown bellow.
a. use only one cell LiPO or LiION batteries!
b. do not use batteries that have leaks or seem to have any damage!
c. do not use batteries without protection circuit!
d. do not change polarities!
a. power supply voltage must be between 4.8V and 7.00V. Do not exceed those values!
b. if you want to use 5V from USB as power source, simply connect Vusb(out) to Vraw pad.
